Thanks for the reminder about 2.0.3.8 @JonMikelV , though we’ll have to find out what @Mushin is running, and maybe when that issue was introduced. Duplicati temp dup-xxxx files not being deleted suggests a 2.0.3.6 regression with a 2.0.3.8 fix, however there seems to be at least some issue in 2.0.3.11 (see my update there).
